RADIATOR FOR HEATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 402,357, dated April30, 1889.

Application filed January 16, 1888. Renewed January 8, 1889. Serial No.295,804. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH SHAOKLETON, of the city and State of NewYork, have invented an Improvement in Radiators for Heating Buildings,of which the following is a specification.

In many places steam at a high temperature and pressure is conveyedthrough the streets in pipes and led into buildings and employed forheating purposes; but the steam being at a high temperature causes theradiating-surfaces to be disagreeably hot, and when the steam is shutoff the radiator rapidly cools.

The object of my invention is to employ circulating water as the heatingmedium in the radiator, such water being warmed by steam-pipes withinthe same. By this means I am able to make use of radiators having alarge extent of heating-surface, and to heat those surfaces to amoderate temperature, and the mass of circulating water retains theheat, so that the radiator will continue to warm the apartment for aconsiderable time after the steam-supply is shut off.

In the drawings, Figure *1 is a vertical section of a radiator with myimprovements applied thereto, and Fig. 2 is a sectional plan at the linew' 00.

The radiatoritself is'to be of any suitable size, audit is composed ofgroups of vertical pipes A, opening at the top into the case B, and atthe bottom into the base 0, and usually this base 0 is supported by acase, D, resting upon the floor, into which the atmosphere is admittedby a pipe leading to the outside of the building, and there is anair-space, E, through the base C, that admits the air to pass up betweenthe ranges of pipes A and become warmed by them and then pass out intothe apartment.

Within the base C there is a steam-chamber, H, one end of which isconnected to the steam-supply pipe K by a cock or.valve, L, and thebot-tom of this chamber H is connected by a pipe, M, and check-valve Nto the lower portion of the pipe K, so that Water of condensation fromthe chamber II runs by the pipe M and check-valve N back to the boileror source of steam-supply.

From the chamber H the heating-pipes P pass vertically withinthe rangesof pipes A. Each of these pipes P is preferably provided with a verticalpartition extending nearly to the top, to insure the circulation of thesteam through each pipe. This partition is well known in steam-heatingapparatus.

It is advantageous to introduce the steam heating-pipes P only in aboutthree quarters of the vertical radiator-pipes A, the otherradiator-pipes A being left without such steampipes, as illustrated inFig. 1. It will now be apparent that when the radiator-pipes A and base0 are filled with water the heat from the steam-pipes P will heat thewater and cause it to circulate rapidly throughout the entire radiator,such water rising in those pipes A which are provided with the steampipes P,

and, passing along through the hollow top case, B, the water descendsthrough those radiating-pipes A which are not provided with steam-pipesP and returns to the base, and so on through the base and up againthrough the pipes A that are provided with the steampipes P. In thismanner I am able to produce a rapid circulation of water throughout theentire radiator, and to maintain such radiator at a temperature adaptedto heat the air without the radiator being objectionably hot, and thisimprovement is available in cases where the steam is supplied throughpipes laid in the street, and also where there is a steamboiler in someportion of the building. In all instances the mass of water in theradiator is sufficient to insure a continuance of the heat for aconsiderable period after the steam may be shut off, thus adapting theimprovement to dwelling-houses, wherein the sleeping apart ments will bekept warm through the night by the mass of water in the radiator evenafter the generation. of steam has ceased in the boiler.

I claim as my invention-* 1. The combination, with a radiator com posedof vertical, pipes with a hollow top chamber and a hollow base connectedby said pipes, of steam-pipes applied within a portion of the verticalpipes and a steamchamber with which the lower ends of the pipes areconnected for heating the water contained in the vertical pipes P,extending up from the the radiator and causing an upwardcirculasteam-chamber H, within the radiator-pipes tion, the returncirculation being through the A, substantially as and for the purposesset vertical pipes that are not provided with forth.

5 steam-pipes, substantially as set forth. Signed by me this 30th day ofDecember, I 5
